CHARLES A. KENWORTHY, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS, TO CONSOLIDATED PATENTS 00., INC., A CORPORATION OF NEW YORK.

DUPLICATOR.

Application filed December 22, 1913.

T 0 all whomit may concern Be it known that I, CHARLES A. KEN- WORTHY, a citizen of the United States, and a resident of the city of New York, county of Bronx, and State of New York, have invented certain new and useful Improvements in Duplicators, of which the following is a specification.

The invention relates to duplicatorsof the class having a duplicating medium of sufficient length to permitone working portion thereof to be shifted out of the way and a new working portion brought into operative position without stopping to remove the ink from the section first used.

The invention has for one of its principal objects to provide an apparatus whereby the taking of impressions is facilitated by means of mechanism performing certain operations which would otherwise have to be done by hand.

The invention consists in the novel construction, arrangement and combination of various elements, devices and parts as hereinafter more particularly described. 7 In the accompanying drawings Figure 1 is a front view of my invention, Fig. 2 is a side view of the same, Fig. 3 is a transverse vertical section taken on the line 33 of Fig. 1, Fig. 1 is a longitudinal section of one of the rollers carrying the duplicating surface, Fqs. 5, 6, 7, 8, 9 and 10 are enlarged detailed views, and Fig. 11 is a sectional View of a modified form of the paper guiding devices all as hereinafter more particularly described.

In carrying my invention into effect in the embodiment thereof which I have select ed for illustration in the accompanying drawings and description in this specification, I provide a base 14, having uprights 15 and 16 rigidly secured at the sides thereof.

Supported in the upright 16, and rigidly secured thereto by the set-screw 17, is one end of a rod 18, said rod extending the width of the machine. The other end of the rod 18 is supported by the upright 15 in ametal 20 substantially semicircular in crosssection (best shown in Fig. The duplicating sheet is stored on the Specification of Letters Patent.

Serial No. 808,212.

' In the accompanying drawings Ihave shown a form of such rollers and of connecting and operating means which I will now describe. Referring more particularly to Fig. 4 the roller will be seen, marked there 22, but it will be understood that the roller 24 may be similarly constructed. Projecting from the center of each end of the roller is a pin 25, and from near the edge of each end two shorter pins 26. Journaled in one of the members 19 is a rotatable member 27, having at its outer end a transverse bar 28 by which it may be rotated, and on the inner portion a ratchet 29 adapted to engage with a pawl 30. The pawl and ratchet is shown enlarged in Fig. 5. The center of the inner end of the member 27 is provided with a socket adapted to receive one of the pins 25 on the is secured a socket, the detailed construction of which is shown more particularly in Fig. (i. The socket consists of a fixed member 32 having a semi-circular bearing. and rigidly secured to the member 19, and a lever 33, pivoted to the member 19 at 34, and held in contact with the member 32 by means of the spring 35. This lever 33 also contains a semi-circular bearing similar to that of the member 32. When the members are in contact the two semi-circular bearings form a journal for the pin 25, and when the lever 33 is pressed away from the member 32 the roller 22 may be lifted from the bearings.

Rotatably mounted on the shaft 18 between one of the members 19 and the support. 16, is a sleeve 40 having secured thereto arms 41 and 45. Journaled in the support 15 is a shaft 42, to the outer end of which is rigidly secured a crank 43. I At the inner end of the shaft 42 is a recess adapted to receive one end of the shaft 18. (The construction is shown by the dotted lines in Fig. 1.) Mounted on the shaft 42, and secured to the same so as to rotate therewith and between the member 19 and the support 15, is a sleeve 44 provided with arms 46 and 47, this construction being similar to the sleeve 40 with its arms 41 and 45. The outer end of the arm 47 and of the arm 45 are rigidly secured to a cross-bar 50. ends of the arms 41 and 46 are rigidly secured to a cross bar 51. The effect of this construction isto produce a rigidrectilinear frame, the ends thereof being formed of the arms 41, 45, 46 and, 47 and thesides being formed of the cross-bars 50 and 51, the said frame being mounted on the shaft 18 in such a manner as to be exterior to the stationary cylindrical frame and to permit of the former being rotated by means of the crank 43.

Journaled in the ends of the arms 45 and 47 and parallel with the cross-bar 50 is a roller 52, adapted to be yieldingly pressed by the springs 152 so as to bear against the surface 23 when the movable frame is rotated. Rigidly mounted on the arm 47, near its end, is a shoe 53, the use of which will be hereafter explained.

Similarly journaled in the ends of the arms 41 and 46 is a roller 62, and in extensions of said arms is journaled a roller 63. These two rollers are geared together at one end, and indicated by 66 (Fig. 1) and the roller 62 is geared by means of'the gear-wheel 64 to a circular rack 65 on the-stationary frame. These rollers do not touch the stationary frame, but when the movable frame is rotated the rollers are also rotated by means of the gear 64 meshing with the rack 65 and the gears 66 meshing with each other. Mounted on the cross-bar 51'is a metal guide 67, (shown in Fig. 3) and mounted on the outer ends of the arms 41 and 46 is another metal guide 68. .This guide 68 is adjusted so as to barely clear the stationary frame. Mounted on the outer end of the arm 41 is a, roller 70, the purpose of which will be hereinafter set forth.

Rotatably and slidably mounted in a perforation in one of the members 19 is a plug 100, held normally in its inner position by a helical spring 101. Located in the inner end of this plug 100 is a square socket adapted to receive one end 102 of a square shaft 71, whose other end 103 is received by a square socket in the inner end of a pin 104 which is rotatably mounted in the other member 19. (This construction is best shown in Figs. 7, 8, 9 and 10.)

Rigidly secured to the square shaft 71 is a metal guide 72. On the outer end of the pin 104 is rigidly mounted a cam 73, (see Figs. 9 and 10). Pivoted to one of the meinbers 19 is a lever 74 provided with a later- Similarly the ally extending pin 75. When the movable frame is rotated this lever is depressed by the roller 70, and in turn depresses the cam 73 by means of the pin 75, thus partially rotating the shaft 71 and raising the outer edge of the guide 72.

Rotatably mounted in brackets on the square shaft 71 and parallel to said shaft 71, is another square shaft 76. 'On this shaft is rigidly mounted a cam 77. On the outside of the said member 19 is pivoted a lever '78, one end thereof being adapted to be moved by the shoe 53, and the other end being provided with a laterally extending pin 179, which is adapted to engage with the cam 77 and thus partially rotate the shaft 76. Mounted on the shaft 76 are fingers 79' which are adapted when the shaft 76 is partially rotated, to bear against the metal guide 72.

Rigidly secured to the support 15 and 16 are two supporting arms ,80. Attached to' these supporting arms 80 is an inclined shelf 81 having its length adjustable by means of the set-screw 82. At the top of this inclined,

shelf is a horizontal shelf 83 adapted to holdthe paper 84 whichv is used in the machine.

Fig. 11 shows a modified form of the devices for removing the paper from the machine after it has been printed upon. In this form the rollers '62 and 63 are mounted in the manner heretofore described, but instead of the guide 68 a modified form of guide is employed, This modified form is designated 168 and is of a double-curved or sigmoid form as shown. This form of guide is better adapted under some circumstances for the purpose of guiding between the rollers 62 and 63 the paper in the duplicating machine, as will be hereinafter fully described.

The operation of my invention is as fol lows: The shaft 71 and. the mechanism mounted thereon are removed from the machine by pulling out the plug 100 against the tension of the spring 101, which action enables the shaft 71 to be lifted out of its bearings. The end of the duplicating sheet 21, which is wound upon the roller 22, is then passed around'outside the sheet metal member 20, as shown at 23 in Figs. 2 and3, and attached to the roller 24, around which it is given a few turns. The surface 23 is drawn taut by means of the ratchet wheels 29. The surface 23 is the partof the sheet from which the impressions are taken. The impression is transferred thereto from the original by placing the original thereon, and passing the roller 52 thereover by rotating the crank 43 and said original is then removed. After having placed the duplieating sheet in the machine, and having transferred thereto an impression from the original of which it is desired to make copies. the procedure is as follows: A sheet of paper or the like on whieh the copies are to he made is taken from the pile 84 on the horimntal shelf 53 and laid on the sloping shelf "*1. its lower portion resting on the metal ,u'uide TL The crank 43 should be in such a position that the roller 52 will be toward the front of the maehine, and the roller 2 toward the rear. The crank t is then rotated in a counter-eloelnvise direction. As 10 the roller 5; reaches the top of the niaohine the shoe comes in eontact with the lever i moving the upper end of the same hack ward. and thus moving the pin 17$) forward The pin 1T1) presses against the lever Ti. thus rotating the shat: To and causing iln fingers T to be depressed upon the guide 72 .w-(ilH'UlV elainping in position the sheet of gainer thereon.
